I'm very impressed with my initial tests with db4o. However, i'm wondering just how many enterprise class websites are out there powered by db4o, i couldn't see any on the main website?
I can't see any reason why db4o should not be used. There appears to be decent enough support for transactions and ways to handle concurrency for example.
Anyone got a list of websites i could look at?
A particular search engine used to be powered by db4o (I say "used to" because I haven't talked to the author about this since a long time).
The author is Travis Reeder.
Although I cannot see websites specifically, here is a list of Open Source Projects from the db4o website:
